NPN LJ12A3-4-ZBX Inductive switch:

The NPN LJ12A3-4-ZBX Inductive Switch is a type of proximity sensor that detects the presence of metallic objects without physical contact.
It works using inductive sensing technology, which generates an electromagnetic field and detects changes when a conductive object enters that field.
This NPN type switch provides a low signal output when an object is detected, making it suitable for position sensing or limit switches in various industrial and 3D printing applications.
It is commonly used in automated systems, including 3D printers for detecting the position of moving parts like the print bed or extruder assembly.
